Title: Adsorptive separation of para-xylene using a tetralin desorbent
Inventor: ZINNEN HERMANN A
IPC: B01J20/18
Filed: 1989-10-27
Abstract: Para-xylene is separated from a feed mixture of C8 isomers of xylene and C9 aromatics by contacting the para-xylene-containing feed mixture with an X or Y zeolite adsorbent having Group IA or IIA cations, e.g., barium and/or potassium, at exchangeable cationic sites. The para-xylene components are selectively adsorbed onto the adsorbent. The non-adsorbed feed is then removed from the adsorbent and the para-xylene recovered from the resulting rich adsorbent by desorption with a desorbent comprising tetralin or alkyl or dialkyl derivatives of tetralin or mixtures thereof. The majority of the C9 aromatics and the C8 xylene isomers are typically recovered in the raffinate andcan be separated from the desorbent by fractionation of the raffinate and the recovered desorbent recycled to the process.

IPC: A61M1/36
Filed: 1989-11-06
Abstract: A method of coating chromatographic particulate supports to provide a biocompatible outer layer of synthetic membrane-type film which prevents the release of fines but permits the adsorption of components to an affinity ligand is described. The matrix is provided with a membrane-type coating, which prevents leaching of fines, with a pore size of at least 20 angstroms. The coating is applied to a solid particulate under conditions where an integral membrane coat will be formed.      It may also be necessary to control the size and number of pores of the membranes by treating a suspension of the solid support in a solvent which contains 0.1-1% of the sugport weight of a biocompatible polymer along with 0.5-5% of the weight of said polymer of a dissolved compatible pore-controlling component. The solvent is then removed from the suspension and the membrane-coated material used in extracorporeal treatment of body fluids or in other chromatographic techniques. The coating process can be conducted before or after the particulate support is functionalized and/or derivatized.

The modem system also includes a receiver section having a circuit for receiving from the telephone channel transmitted signals, a rerotate circuit for rerotating each received waveform substantially to its original condition before rotating, a Fast Fourier Transform circuit for transforming each received, rerotated waveform from a time domain signal back to a frequency domain signal, and a demodulator for demodulating each received and rerotated waveform to recover the digital data transmitted.

Patent CA-2023053-A1 (CA)
IPC: H04B7/26
Filed: 1990-08-10
Abstract: A method of assigning frequencies in a cellular telephone  system  in which  a  first  group  of  the available frequencies is assigned to a first cell, and then distinct groups are assigned to adjacent cells, leaving at least one distinct group of frequencies free for later re-use. This system is applied to each cell in the system, so that for any cell, it and its adjacent cells do not use all of the frequencies in the system.  For a first stage of cell splitting, frequencies  are  assigned  from  at  least  one  non-adjacent cell (using the frequency re-use groups) to at least one part of the cell being split,  while maintaining coverage of the cell from the same cell site. In a further stage of cell splitting in which there are adjacent first and second sets of three co-located  end  radiated  cells,   each  radiated  by directional antennas at first and second cell sites respectively, the cells are split by: locating a third cell site at about the mid-way point between the first and second cell sites; and radiating at least a third cell from the third cell site. An example is given based on 9 cells with sites arranged for end radiation of 3 cells from one site, thus reducing the number of cell sites.  At each site the 3 co-located cells use frequency groups spaced to give protection against adjacent  channel  interference.    The  use  of  end radiated   cells   allows   for   less   co-channel interference, as well as providing for a more distinct handoff between cells.

Filed: 1990-10-09
Abstract: Syndiospecific catalysts and processes for the syndiotactic propagation of a polymer chain derived from an ethylenically unsaturated monomer which contains 3 or more carbon atoms or is a substituted vinyl compound. The catalysts comprise an unbalanced metallocene cation, characterized by a cationic metallocene ligand having sterically dissimilar ring structures joined to a positively charged coordinating transition metal atom, and a stable noncoordinating counter anion for the metallocene cation. One of said ring structures is a substituted or unsubstituted cyclopentadienyl ring and the other of the ring structures is a substituted cyclopentadienyl group which is sterically different from the first cyclopentadienyl group. A structural bridge between cyclopentadienyl groups imparts stereorigidity to the catalyst. The catalyst is contacted with a C3+ alpha olefin or other ethylenically unsaturated compound in a polymerization reaction zone and maintained in contact with the catalyst in the reaction zone under polymerizatio conditions to produce a syndiotactic polymer.

The present compositions are of special value in grand mal seizures, global hypoxic ischemic insults, in hypoxia, alone or in combination with blood flow reduction (ischemia) as well as in cases of cardiac arrest and in cases of abrupt occlusion of cerebral arteries (stroke).      Some of the compounds according to formula (I), as will be hereinafter described in detail, are novel compounds and are claimed as such within the scope of the present application.      The active ingredient of the pharmaceutical compositions according to the present invention is a compound of the general formula;    having the (+)-(3S,4S) configuration, wherein A----B designates a 1(2) or a 6(1) double bond, R designates CH3 or CH2OH, R1 designates a hydrogen atom or a lower acyl group, and R2 designates (A) a straight-chained or branched C6-12alkyl radical; or (B) a group -O-R3, in which R3 is a straight-chained or branched C5-9alkyl radical or a straight-chained or branched alkyl radical substituted at the terminal carbon atom by a phenyl group.      Compounds of formula (I) in which R designates CH2OH and R1 designates a lower acyl group are novel compounds.
